Treading on Google’s footsteps, Swift has now been made Open Source by Apple. Being open source means that people can customize the language easily and just like Android, develop apps without the need for Apple to look over every development.

What is Swift?Swift is a compiled programming language introduced by Apple for iOS development in 2014. Ever since it has expanded and many user have used for many app developments.

If you ever tried to design apps and programs but found it difficult to do so, then here is the solution to your problem. And now this solution is open source and available freely to all. Yes, that’s true.

Apple states that the language ‘Swift code is interactive, concise yet expressive’. For developers looking to build on the iOS platform, the software is a powerful weapon for designers and developers to develop applications that are unique and yet simple. This language works alongside Objective-C, which alone lacks user-friendliness.

Easier to create appsNow that this language has become open source and its compiler is public, developers can recreate the compiler as per their requirements. The iOS apps would become compatible for the non-Apple interfaces.

Observing the present scenario in the app development industry, Swift is being used for many programs and is expected to be the background for many applications shortly.

Swift is modern, cleaner, powerful yet simple and interactive. Still there are certain limitations to its source code. This is because it is quite efficient until its libraries are unaltered.

Lately, the policies were amended to provide deeper access to the hardware and the in-built apps, lowering the sandbox walls to allow apps to communicate and form the web to let the apps work together and conclude into a platform that can help achieve new solutions.

Integration made simplerThese have let the apps like Apple Maps link to the Siri, iCloud the mail and many more. These policies have not just brought new apps, but these have given an opportunity for the developers to design apps on a platform that would not be specific to just one environment.

Identification of errors and bugs would become simpler and thus it makes swift a language of the common man. Open source would also be an advantage to the language since its source code is available to the public, it can be reshaped. These additions can improve the language and these can help develop new products.

The freedom given to the developers would remove all the restrictions that they face due to copyright issues and limited access. Now better apps can be made.

Apple’s senior VP Mr. Federighi had some interesting words when asked about what Swift would mean to iOS developers. ‘We think Swift is the next big programming language, the one we will all do application and systems programming on for 20 years to come. We think it should be everywhere and used by everyone.’ Apple’s focus on making Swift the next big programming language is unmistakable, a fact that the programming language is already in the top 20 programming languages now.

It has been seen that open source programs have led to great developments for the OS, like Google’s Android. We do look forward to such response from the Swift.

How effective is your landing page? For companies who are serious about results, the sure shot way to know more about results is through a comprehensive A/B testing strategy. A/B testing involves subtly changing various things on the landing page and seeing the audience response to each. For instance, the text may be changed or even the text color - to better user engagement. It's been seen, for instance, that a direct call out like 'Download it now!' at the end, helps achieve a better conversion ratio most of the times.

A/B testing is an amazing tool for researchers and developers who like to make test-driven decisions for products. A/B testing has been in the industry for quite some time now. For app developers though, A/B testing has got a new lease of life. Presently, the testing is gaining popularity because it allows developer or mobile marketers analyze and understand various aspects of users’ behavior after Google allows App Analytics. To use A/B testing effectively, a marketer must avoid a few mistakes.

1. Not tracking right metricsBe careful when you make changes to your content. Changes in the content can lead to increase or decrease of conversions and clicks. You will have to track the right metrics to understand the changes. In addition, you have to track enough metrics to know the reason of changes. Understanding or tracking too many metrics won’t be good as some are bound to mislead you with positive results. Concentrate on the core metrics to determine if your test was success or failure. Understand what metrics to track and ensure that there is enough information to help your improve your product.

2. Plan out the user requirements firstAlways do the mathematics first. Always do a rough estimation of the number of users needed for your test. Determine the period of the test. This evaluation will help you design the variants of testing. You will understand where more users are required, and other tweaks are required.

3. Stopping the test before you shouldMany are always are in hurry to see the results and hence they end the A/B testing early. The biggest disadvantage of stopping the test early is that they can offer you false answers. This happens because, in a short period, there will not be enough test pool to give an accurate result. Try to run the test for a month or more to have results that are more accurate and truthful.

4. All users behave differentlyThe biggest mistake that is made while using A/B testing is considering all the users as same. However, since all users are not same, you will have to create various versions of tests. Hence, you will have dive deeper to gain much better insights. Use segmentation and user targeting will be useful.

A/B testing tool will be of great use if you avoid such mistakes learn more ways to use the tool more effectively. You surely do not want to miss a great opportunity to improve your app.
